SECURITY DEVICE FOR TRAILER DOORS
FIELD OF THE INVENTION
The present invention relates to a security device and more particularly, relates to a security device to be used with the doors of a trailer.
BACKGROUND OF THE INVENTION
Trailers for towing behind a vehicle are well known in the art. They come in various sizes and configurations and range from small trailers utilized by consumers to larger trailers which are typically utilized by contractors. Trailers are typically used for carrying parts and tools which a contractor will typically require when working on site.
An extremely prevalent problem which presents itself to most contractors is the theft of equipment from the trailer. Such thefts can occur if the trailer is left on site unsupervised, such as may occur during the overnight hours or even during working hours.
There are different known arrangements for locking the trailers. One popular arrangement is one wherein a vertically extending bar locks into both the top and bottom frames of the trailer proximate the door opening. In such an arrangement, there is provided a horizontal bar which is used to rotate the vertical post into and out of a locking relationship with the trailer. The horizontal bar is then typically secured between two hasps, at least one of which is movable to allow movement of the bar to rotate the vertical post.
The two hasps are typically secured together by means of a lock.
Problems arise with respect to the above arrangement. Thieves have become very adept at picking such locks or just cutting them off to gain access to the contents of the trailer. Furthermore, often the lock is not securely fixed due to the inattention or laziness of employees accessing the trailer.
It would therefore be desirable to have a security device which overcomes the above recited problems and which security device is easy to use and would automatically lock the trailer doors once activated.
SUMMARY OF THE INVENTION
According to one aspect of the present invention, there is provided a security device for a trailer door, the security device having a rotatable post for locking the door, a bar member attached to the post, the security device comprising a plate member for securement to a substrate, a cover hingedly connected to the plate member and movable between an open and closed position, a locking device mounted at one end of the cover, the locking device having a housing, a plunger mounted within the housing, the plunger being movable between an extended position and a retracted position, the plunger being spring biased to the extended position, and a deflector extending upwardly from the plate member, the deflector having an aperture formed therein, the plate being located such that the plunger enters the aperture when the cover is in a closed position.
Typically, the known trailers are secured by inserting a lock between two hasps, which lock a horizontal bar used to rotate a vertical post between locked and unlocked positions.
The security device of the present invention functions to prevent access to the hasps.
The device will include a member enclosing the hasps and which member is formed of a suitable material such as stainless steel.
In greater detail, the security device utilizes a plate member which is secured to a substrate. Typically, the substrate will be the door itself although some arrangements could utilize a portion of the trailer wall.

SUMMARY OF THE INVENTION
According to one aspect of the present invention, there is provided a security device for a trailer door, the security device having a rotatable post for locking the door, a bar member attached to the post, the security device comprising a plate member for securement to a substrate, a cover hingedly connected to the plate member and movable between an open and closed position, a locking device mounted at one end of the cover, the locking device having a housing, a plunger mounted within the housing, the plunger being movable between an extended position and a retracted position, the plunger being spring biased to the extended position, and a deflector extending upwardly from the plate member, the deflector having an aperture formed therein, the plate being located such that the plunger enters the aperture when the cover is in a closed position.
Typically, the known trailers are secured by inserting a lock between two hasps, which lock a horizontal bar used to rotate a vertical post between locked and unlocked positions.
The security device of the present invention functions to prevent access to the hasps.
The device will include a member enclosing the hasps and which member is formed of a suitable material such as stainless steel.
In greater detail, the security device utilizes a plate member which is secured to a substrate. Typically, the substrate will be the door itself although some arrangements could utilize a portion of the trailer wall.
- 2 -The cover is hingedly connected to the plate member and is movable between open and closed positions. In the open position, access is provided through the hasp and bar member to lock or unlock the door as desired. In the closed position, access to the hasp is denied and the trailer is secured.
The cover is preferably designed to have its hinge arranged at the upper portion of the cover. The hinge arrangement is preferably one wherein the cover may be maintained in the open position without human intervention. A number of arrangements can be used including one wherein the hinge and cover, when in the fully open position, require a greater than normal effort to close the cover.
The cover preferably includes an interior wall to form a compartment therein.
A
sealing material may be utilized such that when the cover is in a closed position, a moisture impermeable barrier is formed to prevent moisture entering the compartment.
The locking device is mounted in one end of the cover, the locking device having a housing with a plunger mounted within the housing. The plunger is movable between the extended position and the retracted position with the plunger being spring biased to the extended position.
The deflector extends upwardly from the plate member and has an aperture formed therein. Preferably, the plate member has an angled portion which will contact the plunger when the cover is moved from the open to closed position. This will allow the plunger to be guided downwardly where it will enter an aperture formed in the deflector.
The locking device is of the push-pull type wherein once a key is entered therein, an inner housing containing the plunger may be retracted. This will permit opening of the cover and access to the bar member.
